VAPORIZER.

SPECIFICATION forming partof Letters Patent No. 629,390, dated Jul 25,1899.

Application filed May 8, 1899. Serial no. 715,935. (No model.)

To all who-7n it may concern:

.jurious to the user. by means of the construction illustrated in Be itknown that I, BYRON S. PALMER, a citizen of the United States ofAmerica, and a resident of the village of Glens Falls, Warren county,State of New York, have invented certain new and useful Improvements inVaporizers, of which the following is a specification.

My invention relates to a vaporizing device for the purpose of applyingmedicine to such portions of the body as the eye, ear, nose, and throat;and the objects of my invention are, first, to produce a vaporizer inwhich diiferent medicines may be used by removing the inner cylinderwhich contains onemedicine and inserting cylinders containing othermedicines in the same vaporizer; second, to so construct a vaporizerthat it may have several inner cylinders charged with medicine,

so that when the medicine is exhausted from' one inner cylinder thevaporizer may be recharged by simply removing the exhausted cylinder andinserting a fresh one and returning the exhausted cylinder to themanufacturer or the physician furnishing the same to be recharged, andthus avoid the incon-. venience and loss of the use of the vaporizerwhile it is being recharged, and, third, to so construct my vaporizerthat the powerful medicines used will not so act upon any part of it asto produce a vapor which'will be in- I attain these objects theaccompanying drawings, in which-'- Figure 1 represents a sideelevationof my vaporizer. Fig. 2 represents a vertical section. Fig. 3 representsa top plan view, and Fig. 4. represents a horizontal section at-X X onFig. 2.

Similarletters refer to similar parts throughout the several views.

My vaporizer consists of an outside shell or case A, made in the commonform of a vaporizer or inhaler, having. caps G G, which when removedleave a clear space through the entire center from the bottom to thetop. The bottom D screws off, so as to leave the shell or case A open atthe bottom. V

Bis an inner cylinder, which is inserted in the shell or case A when thebottom D is removed and' has tubes on each end to fit in the upper andlower tubes of the shell or case A, which can be closed by caps similarto the caps G G when the cylinder B is not in use or inserted in theshell or case A, but which caps are removed when the cylinder B iswithin the shell or case A.

I C is a perforated hollow cylinder the length of the cylinder B and ofthe size of the two projectingtubes of B.

E is a cap which forms the entire bottom of the inner cylinder B andwhich can be re moved for the purpose of inserting the perforatedcylinder G and the absorbent H.

H is an absorbent, preferably constructed of asbestos raveled out orpicked to pieces, and ispacked compactly around the hollow cylinder (Jin the inner cylinder B, and when thus packed the medicine which isdesired to be applied is poured upon the absorbent H until the absorbentH becomes saturated as much as is desired.

Many of the medicines used are of a powerful nature, and if they come incontact with certain metals, such as tin or brass, or with jointssoldered together they produce a poisonous or injurous vapor. Thereforeto prevent any such undesirable action,which often neutralizes orrenders positively harmful the administration of medicine by such means,I make the inner cylinder B and the perforated cylinder G of aluminium,which is noncorrosive and unaffected by the medicines used, and byspinning these parts from aluminium or stamping them from the sheetmetal without joints the medicine comes in contact with no other portionof the vaporizer and with no other foreign substance. When thus made,several inner cylinders may be used with the same vaporizer, and byhav-' mg interchangeable cylinders the same instrument may be used fordifferent forms of medicine and for different purposes, and by removingone cylinder from the vaporizer it can be replaced by another chargedfor an entirely difierent purpose or one having an result will beattained.

use ofother instruments of a like character. When the cylinder B ischarged with the medicine desired to be applied to a particular part,the bottom D of the vaporizer is removed and the cylinder B inserted andthe bottom D returned to its place. Then the caps G G are removed fromthe cylinder, leaving a clear course for adraft of air through thecylinder. Then one end of the vaporizer is placed at or near the part towhich the medicine is to be applied. The draft of air will carry thevaporized medicine from the absorbent through the vaporizer,and thedesired WVhen the vaporizer is not in use, the caps G G are returned totheir places, so as to prevent the medicine from Wasting.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A vaporizer consisting of an outer shell or case, having projectingtubes at the bottom and top; caps to inclose said tubes; an innercylinder adapted to hold an absorbent material and readily removablefrom the outer shell or case; a perforated cylinder extend- .inglengthwise of said inner cylinder, around which the absorbent may bepacked in said inner cylinder, leaving a clear, open space through thecenter of the entire vaporizer, between the two caps of the shell orcase, substantially as described and for the purposes set forth.

2. In a vaporizer, the combination of an outer shell or case, havingprojecting tubes at the center of each end; caps to fit said tubes; aninner cylinder with projecting tubes at the center of each end,corresponding with and fitting into the projecting tubes of the case,said cylinder having a removable bottom; a perforated, hollow cylinderextending from one tube to the other of the hollow cylinder, leaving aclear,'open space between the said tubes; an absorbent material packedabout said perforated cylinder, within said inner cylinder; the bottomof said outer shell or case being capable of being removed,substantially as described and for the purposes set forth.

3. A vaporizer for medicinal purposes, consisting of an outer shell orcase, having projecting tubes on each end, inclosed by caps, incombination with an inner cylinder stamped or spun from aluminium, saidcylinder having a removable bottom and no other joints, and, havingtubes on each end to correspond with and fit into the tubes on saidcase; a perforated hollow cylinder of like material, extending from onetube to the other of said inner cylinder an absorbent material packedaround said perforated tube, adapted to hold vaporizing medicine, andmeans for removing the bottom of said outer shell or case, sufficientlyfor inserting said inner cylinder, substantially as described and forthe purposes set forth.
